Is it a bug?: I get the following error on this kata:

Test Results:
Unable to decode the command from the command line:
UnicodeEncodeError: 'utf-8' codec can't encode character '\udcc3' in position 293: surrogates not allowed
STDERR:
Unable to decode the command from the command line:
UnicodeEncodeError: 'utf-8' codec can't encode character '\udcc3' in position 293: surrogates not allowed

Using Python, got the following results
"✘ 'tuijrui piijlaqqrjyistlagjktpudh oselowytqauupokkiyagyhhqha lhphiahopq' should equal
'tuijrui piijlaqqrjyistlagjktpudh oselowytqauupokkiyagyhhqha lhphiahopq'"

obviously, the problem is the multiple spaces in the middle. The instructions say nothing about maintaining extra spaces. If extra spaces are not to be dropped, which substring does it go with? The substring it comes after, or the substring it comes before?
